'GAS-GENERATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 366,168, dated July 5, 1887.

Application filed April 3, 1886. Serial No. 197,698. (No model.)

To ctZZ whom it 11i/wy concern:

Be it known that I, LoUIs Grinsen HUBER, a citizen of the United States, resident at Huber, in the county of Bullitt and State of Kentucky, have invented certain new and useful ImprovementsiuGas-Generating Machines; and I do declare the following to be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or gures of reference marked thereon, which form a part of this specification.

Figure l represents a side elevation of the machine, showing the tubing between the pans. Fig. 2 is a central vertical section of the same. Fig. 3 is a plan view of the bottom pan. Fig. 4 isa plan view of one of the pans thereabove. Fig. 5 is a section showing the construetionof the evaporating material. Eig. 6 is a central vertical section of the bottom pan, also illustrating the construction of the top pan. Fig. 7 is a side view, broken, of one of the glass gages. Fig. 8 is aside view of one of the tube attachments, by means of which the oil can escape from one pan to the next below. Fig. 9 is a perspective View of one of the pans between the lowest and highest. Fig. 10 is a detail view of one of the supports between the pans. Fig. 11 is a vertical sectional view of Fig. 8.

My invention relates to carburetingniachines; and itconsists in the construction and novel combination of parts, as hereinafter described, and pointed out in the claims.

I am aware that it is not new, broadly, to combine with a carburetor-case a perforated air-chamber in the door thereof, pans arranged above and with air-chambers, and having outflowpipes and flues arranged in said pans at their peripheries, and upper perforated airchamber, gaschamber above the said perforated chamber, and means for supplying` the lower air-chamber with external air.

Referring byletter to the accompanying drawings, A designates the gas-generator, which is provided with the cone-shaped top A', which forms au unobstructed gaschamber, A2, immediately over the upper or rst oil-pan, A3. A short piece, A4, of pipe is soldered into the cone-shaped top A, barely passing through the top, and enters the gas-chamber A2. To this pipe A'L is connected the pipe A, which leads to the house, whereby the gas is distrib uted throughout the intermediate pipes connecting with the burner. The central pipe, A, is connected with the airpump,and through this pipe AG the air passes tothe bottom of the generator before coming in contact with the oil. In passing upward toward the gaschamber through the vertical lines S S, Src., the air is forced to take a zigzag course over the surface of the oil in each of the oil-pans l, 2, 3, 4, and 5, containing the textile or absorbing substance, and by this process by the time the air has reached the gaschamber it is thon oughly carbureted, and is ready to pass into the gas-pipes to be consumed at the burner.

`The construction of pans Nos. l and 5 is the same, excepting that'No. 1 has double the capacity of No. 5. Cock A7, Fig. 1, enters pan No. 5 just below the top of said pan, and is for the purpose of ascertaining when said pan is full of oil. Cocks B B B2 B3 B1v are in counection with the fixture B5, as shown in Fig, 8, which fixture enters the lower portion of one pan and the upper portion of the next pan immediately below it. The object of these cocks is to permit the oil to be drawn entirely out of each pan in the'generator when desired.

E F G H are the pan feed-pipes, which are provided with stop-cocks E F G H', any one of which may be opened to enable the oil to be drawn from any desired pan to another pan below it, to supply depleted pans with fresh oil and to pass all heavy oil to the bottom pan when refilling, as required. The glass gages X are for the purpose of showing the quantity of oil in each of the paus. vCock iD enters the bottom pan, and, being left open while the machine is being lled, is a guide to show when the pan is full by the oil running out at said cock D. The pipeH2 is the oil-filling pipe and passes through the top of the generator, and down into the first pan, l, at the point marked 3. V

In Fig. 2 I have delineated a vertical section of the generator, showing theinternal an' rangement of the evaporating-pans, the airchambersU U, the fines S, air-pipe A,` and the overflow-pipesV in the bottoms of the pans.'

IOO

convenient points to the sides of the generator.

In machines of large diameter supports a, as shown in Fig. 10, are soldered to the bottom pan and extend to the bottom side of the next pan above, and on the bottom of the next pan, and in line with the support a in the bottom pan, is a second support, c, which extends up to the bottom of the next pan and is soldered in like manner, and this system of supports is continued until a'column is formed from pan to pan and the entire set of pans is supported.

Pans 2, 3, and 4 are similar in construction. They are each lprovided with four semicircular openings, S, which form flues for the pas sage of air and gas. The central opening, X2, is the opening through which the air-pipe AG passes. Vires X radiate from the centers to the circumferences of the pans, t-heheavy lines representing the radial wires near the bottoms of the pans and the lighter radial lines representing the wires near the top. The object of this wire frame, constructed in the manner described, is to utilize every square inch of the pan for weaving the evaporating material, jute, on an advantage not heretoforeobtained in this class of generators. Pan No. 5 has no overflow-pi pe. The overiiow-pipes V in those pans which are therewith provided are j ust a little shorter than the height of the pans they are in, and the pipes V pass through t-he bottom of the pans. The overliow-pipes V dodge each other in the intermediate pans, and, in addition to acting as a medium to allow the oil to pass through them to each pan as each pan is in turn filled by them, they act as lues for the passage of air and gas up through and over the surface of the oil in each of the pans.

Pans 2, 3, and 4 contain the semicircular ilues or openings S in addition to the overflowpipes V. These iluesSare so arranged in each pan as to have no one ue immediately opposite the other, but alternating,so as to have the effect of further distributing -the air over the surface of the' oil and evaporators.

G L designate the glass-gage fitting, Z being the packing-box, the cap Z being screwed down into the opening through which the glass tube Z2 passes. This fixture is of castbrass and is open throughout its entirelength, except when closed by the glass tube and caps. The tube Z3 connects the glass tube with its proper pan, so that the oil in the pan Will flow through into the glass tube, and will show in the tube the level of the oil in the pan.

The operation of the invention is as follows: After having located the generator and airpump to light the building, the air-pump being connected to the air-pipe in the top of the generator, and the gas-pipe leading into the scales house being connected with the gaspipe of the generator, oil is poured in the generator through the oil-ill, and when it rises to a suficient height to pass off through the overflowpipe leading into the second pan this pan is lled by the overdow from the first pan. This system of overflowing from pan to pan is kept up until the oil runs from the cock D, which is the overflow-cock, and shows that the whole system of pans is full. Each of the pans, as heretofore described, contains evaporating material with the proper air chambers and lines. The pressure of air from the pump passes down the air-pipe to the air-chamberin the bottom pan, and, passing out of this airchamber through the perforations p in its top, strikes the jute on the wire frame, said jute being saturated with oil,and carries the evaporated oil up through the openings in each pan until the gas-chamber is reached, when the air and gas are so thoroughly assimilated and mixed as to form by the combination ahighly illuminating gas, known as carbureted-air gas. The gas at this point is ready to pass out of the generator and into the pipes and burners throughout the house to be consumed at the burner. A steady pressure of air is kept up by the air-pump, which is kept in operation by weight power, until all of the lights have been turned off 5 then the generation of gas ceases and the action of the pump stops until one or more burners are lighted. The supply andrdemand of air and gas are at all times equal. After the generator' has been lled with any of the gas-producing oils-wiz., naphtha, mineral oil, Src-and the airpump wound up, the generation of gas and the action of the pump are entirely automatic.

Pis a pipe running horizontally with the casing, with its inner end within the air-receptacle in the bottom pan. The outer end of said pipecan have the air-.pump attached thereto, if desired, and when it is not con venient to attach the same to a vertical air tube. The pipeP in practice has an inwardlyopening valve at its outer end.
